How to implement Stripe or Braintree for Xamarin Forms?

I tried to implement Judopay, and everything went well, but in the end, they refused to offer their service because my app is apparently a “high risk”, so I’m looking for another solution.

I tried Paypal.Forms but direct card payments won’t work because the solution has basically been deprecated.

I see no tutorials for Braintree or Stripe for Xamarin Forms and I’m new so I cannot simply create my own implementation for Braintree based on Braintree.iOS and Braintree.Android

My best option right now is to try and follow https://www.google.com/amp/s/xamarinhelp.com/stripe-in-xamarin/amp/ but I’m having difficulty following the tutorial.
